High voltage power supply

Abstract

A power supply for transmitting voltage to a device, including a web having a piezoelectric exterior layer for generating a voltage on the surface thereof in response to being deformed. The web is entrained about a roller arrangement to deform the piezoelectric exterior layer. Commutation brushes transfers the voltage generated on the surface of the piezoelectric exterior layer to the device. The roller arrangement in combination with the placement of commutation brushes and neutralization brushes are used to adjust the voltage to the device.

We claim: 
     
       1. A power supply for transmitting voltage to a device, comprising: a web including a piezoelectric exterior layer for generating a voltage on the surface thereof in response to being deformed;   a member for deforming a portion said web;   means for transferring the voltage generated on the surface of said piezoelectric exterior layer to the device;   means for neutralizing the voltage on a portion of the surface of said web; and   a voltage control, operably associated with said transferring means and neutralizing means, for adjusting the voltage by a set factor to the device.   
     
     
       2. The apparatus of claim 1, wherein said voltage control comprises polarity changing means for changing the polarity of the voltage to the device. 
     
     
       3. The apparatus of claim 1, wherein said member comprises a plurality of rollers, said web being entrained about said plurality of rollers to deform said piezoelectric exterior layer. 
     
     
       4. The apparatus of claim 1, wherein said transferring means includes a plurality of conductive brushes coupled to said web. 
     
     
       5. The apparatus of claim 1, wherein said transferring means includes a conductive roller coupled to said web. 
     
     
       6. The apparatus of claim 1, wherein said neutralizing means comprises a plurality of conductive brushes coupled to said web. 
     
     
       7. The apparatus of claim 1, further comprising means for moving said web at a predetermined velocity in the direction of movement. 
     
     
       8. The apparatus of claim 1, further comprising current adjusting means for adjusting a current level to the device. 
     
     
       9. The apparatus of claim 7, wherein said current adjusting means comprises means, responsive to said moving means, for adjusting the velocity of said web. 
     
     
       10. The apparatus of claim 1, wherein said piezoelectric exterior layer comprises a layer of piezoelectric polymer film. 
     
     
       11. The apparatus of claim 1, wherein said piezoelectric exterior layer comprises: a first layer of piezoelectric polymer film having a first polarization direction; and   a second layer of piezoelectric polymer film having a second polarization direction opposed to the first polarization direction.   
     
     
       12. The apparatus of claim 1, wherein said voltage control comprises a plurality of said transferring means and a plurality of said neutralizing means being positioned along deformed portion of said web and nondeformed of said web. 
     
     
       13. The apparatus of claim 12, further comprising a, and wherein said set factor is a whole number less than or equal to the number of said plurality of said member employed.
